Five months of Anderson summer heat
From May through September, your air conditioner runs almost every day, working against afternoons that average 89°F. That is five months of steady load on the compressor, longer than a lot of the country asks of one.
A new system installed today has to meet a federal minimum of 14.3 SEER2, so it starts out more efficient than what it is replacing. It also has to hold up under Anderson County storms. The area has logged 111 damaging wind events and 33 hail events over the past ten years, with hail up to 1.75 inches. Whatever gets installed sits outside through all of that.

- What size air conditioner does my house need?
- The right size comes from a load calculation, not a rule of thumb based on square footage alone. A contractor measures your insulation, window area, ceiling height, and how much shade your house gets before landing on a number. An oversized unit cools the air fast but shuts off before it pulls humidity out of the house, and an undersized one runs constantly through the summer without keeping up. With highs here averaging 89°F for five months, getting this number right matters more than in a place with a short cooling season.
- Should I replace the whole system or just the outdoor unit?
- If the indoor and outdoor units were installed at the same time and one has failed, replacing both together is usually the better path. The compressor outside and the coil inside are matched to work at a specific capacity and efficiency, and pairing a new outdoor unit with an old indoor coil can mean it never runs the way it was designed to. Age matters too. A contractor can look at both parts of your system and tell you whether the indoor coil is worth keeping or whether it will just shorten the life of a new outdoor unit.
- Do HVAC contractors in Anderson need a state license to work on my home?
- Yes, HVAC contractors doing this work need a state license. Ask to see the license number before any work starts, and check that it is current. A licensed contractor has also passed inspections and carries the insurance that protects you if something goes wrong during installation.
